All the sea caves found in the world, Limestone Caves are the most common type. Their formation takes place when rain water picks up carbon dioxide in the air to form a weakened solution called carbonic acid. The presence of this acid in the water eats away at the limestone gradually dissolving it over time to create a cave.

Some Limestone Caves also owe their existence to the process of corrosion where particles found in large amounts of running water or waves grind away at the rocks to wear them away consequently allowing them to take shape. The sheer beauty and enormity of Limestone Caves draw people to it in amazement and wonder. Not only are Limestone Caves common but they are also in majority in many areas of the world. Featured below are some of the most fascinating Limestone Caves.
